PISTOL.

Specification of Letters Patent.

Patented Apr. 27,

To all 'whom t may concern:

Be it known that I, GEORGE S. LEWIS, a citizen of the United States,residing at Springfield, in the State of Massachusetts, have inventedcertain new and useful Improvernents in Pistols, of which the followingis a specification, reference being had to the accompanying drawings,forming a part hereof.

This invention has for its object to produce a lsingle-shot pistol,particularly adapted for target shooting, of simple, inexpensiveandrigid construction, the details ofimprovement being pointed out moreparticularly hereinafter, with reference to the accompanying drawings inwhich the invention is illustrated and in which- Figure 1 is a top viewof the pistol closed.

Fig. 2 is a view of the same in vertical, longitudinal, central section.

Fig. 3 is a detail view of the barrel lock.

Fig. 4 is a view similar to Fig. 2, but showing the pistol broken.

Fig. 5 is a detail view in section on the lane indicated by the brokenline 5-5 of ig. 2, looking in the direction of the arrows.

F ig. 6 is a detail view in section on the plane indicated by the brokenline 6-6 of Fig. 4, looking in the direction of the arrows.

The pistol comprises two main parts, the frame a, chambered at a', asshown clearly in Figs. 2 and 4, with its grip pieces a2 secured by boltsas, and the barrel b secured in its sleeve or carrier b which is pivotedin the frame at b2. In the left-hand side of the frame, as shown inFigs. 1 and 3, in a recess a4 is pivoted on a screw c', a triangularbarrel-latch c, provided with a milled surface c2 and normally thrownforward by a spring which is shown in part at c4, so that its nose c5may engage a re cess b3 formed in the side of the barrel or its carrierb. To release the barrel, the latch is pulled back and when the barrelis again swung to a closed position it first presses the latchrearwardly and is then engaged by the latch in its closed position, thelower edge of the latch being curved on a slightly eccentric arc so thatit shall engage the barrel with a cam-like action and so preventpossibility of movement of the barrel with respect to the frame wlpistol is closed.

In the under-side of the carrie: formed a dove-tailed groove b4, clearlyin Figs. 4, 5 and 6, which i the extractor d formed at its rear at d',to enter the recess b in the the carrier and the end of the barn toengage roperly the cartridge, as clearly in ig. 2. A dog d2 is piv aslot a5 inthe forward end of the a, having a flat heel d3 to limit the imovement of the dogy when the I; opened by contact with the rear wa theslot, and having a nose d* whicl the barrel is closed, enters the slot Zdog is normally pressed forwarc' spring-pressed plunger d5 which is n inthe frame, the forward movemen plunger being limited by a pin d". thepistol is closed the extractor d dog d2 occupy the positions shown 2,but when the pistol is broken t d4 of the dog, during the first parlbreaking movement, engages the end of the extractor d and moves tivelyto the barrel, as shown in During the last part of the breakin ment ofthe barrel the dog Z2 ren rest by reason of the contact of its d3 withthe rear wall a6 of the slot therefore its nose clears the forw` of theextractor d when the barrel the position shown in Fig. 4 so th acartridge is fully inserted in the of the barrel and the extractor isforward its forward end acts aga inclined or cammed surface Z7 of d2 andthrusts the dog backward an ward out of the path of the e: Finally, whenthe barrel reaches tl position shown in Fig. 2, the forw of theextractor clears the nose of and permits it to be snapped up springplunger d5 into the position s Fig. 2 in readiness to engage the f inthe next breaking movement barrel.

It will be noted further that the f d is formed with an inclined orsurface d8, best shown in Fig. 4, in the closing movement of the b:incline d8 strikes the frame at tf a7 and thereby the extractor is thr`ward and does not interfere with the closing movement of the barrel. Themovement of the extractor in each direction is limited b a pin d, theend of which travels in a s t b5 in the under-side of the carrier b.

The hammer e is pivoted in the frame, is acted upon by a main spring eand plunger e2 and is controlled by a combined trigger and sear e3,acted upon by a springpressed plunger e4, all substantially as usual.The hammer is completely inclosed within the chamber a of the frame andis connected by a link e5 with the finger-piece e which is extendedrearwardly through the frame so that the hammer can be cocked. Thehammer acts as usual upon the firing pin f. The rear sight g, is shownin position in Figs. 1,2 and 4.

It will be understood that changes in the form and relation of parts maybe made to suit di'erent conditions of use or the convenience of themanufacturer and that the invention is not limited to the preciseconstruction shown and described herein except as pointed out in theclaims.

I claim as my invention:

l. In a pistol, the combination of a frame, a barrel pivotally mountedon the frame, an extractor slidingr on the barrel, and a dog pivotallymounted on the frame and having a flat heel to coperate with theframe-to limit the swinging movement of the dog and provided with meansfor cooperation with the extractor in the forward movement of theextractor whereby the dog is moved out of the path of t to permit fullforward moven the dog being free to engage t again when the closingmove: barrel is completed.

2. In a pistol, the combinatioi a barrel pivotally mounted o1 anextractor sliding on'the barr pivotally mounted on the fra] ing a noseto engage the extr: inclined or cammed surface or above the nose tocoperate tractor in its forward movexn the dog is swung rearwardly outof the path of the extract full forward movement thereof ing free toengage the extracto the closing movement. of the b pleted.

3.
